摘要
在用马氏体点变化法测得ＺＧ０Ｃｒ１３Ｍｎ８Ｎ钢奥氏体中碳化物等温析出动力学曲线（ＰＴＴ图）的基础上，研究了冷却速度对ＺＧ０Ｃｒ１３Ｍｎ８Ｎ钢中碳化物连续冷却析出动力学的影响，并获得了该钢奥氏体中碳化物连续冷却析出动力学曲线（ＰＣＴ图）。
Based on the measurment of isothermal precipitation kinetics curves of carbides in austenite (PTT curve), the effect of cooling rate on the carbide precipitationkinetics in austenite under continuous condition for ZG0Cr13Mn8N steel was investigated by ΔMs method, and the corresponding precipitation kinetics curves (PCT curve ) are obtained.
